Patent DE-4138663-A1 (DE)
Inventor: SCHIELEIN MICHAEL
IPC: G06T5/00
Filed: 1991-11-25
Abstract: Segmenting continuous fields in screen images is often part of a problem to be solved in various image processing applications. The invention relates to a process for segmenting a continuous field with diffuse edging in a monochrome screen image which is especially tailored to the segmentation of fingerprints and similar image material. Here, firstly a framing rectangle is found in the centre of which an average intensity is obtained within a window. A threshold is calculated from this average image intensity and all blocks within the framing rectangle are marked in which at least one image point exhibits an intensity below this threshold.

Title: Power amplifier for HF and HV output - has push=pull power MOSFETS as output devices driven by symmetrical supply voltages via pre-amplifier circuits
IPC: H03F1/52
Filed: 1991-12-06
Abstract: The power amplifier has a pair of identical MOSFET transistors (1,2) with a driver circuit (11, 12) each and a preamplifying stage (16). Each MOSFET is fed by a symmetrical power supply (5) of 200-1000 V driven by a current of few amperes to a load impedance (10) over a frequency in the range of 100 KHz to 1 MHz. The driver circuit brings the gate-source voltage of the MOSFET transistors to a level of 2-6 V. The pre-amplifier circuit with a feedback divider (17, 18) is coupled to the driver circuits. A current sensing resistor (4) and a regulator circuit (13) ensure that the load current, Il, does not exceed a pre-set value and does not damage the output MOSFET transistors. USE/ADVANTAGE - High electrical performance of amplifier makes it ideal for ultrasonic transducer driving.

Patent DE-4229148-A1 (DE)
Inventor: RIEDER KLAUS-HARTWIG
IPC: G01R25/08
Filed: 1992-09-01
Abstract: A digital phase comparator measures the phase difference of two signals (S1, S3) from a third signal (S2), and calculates the difference.

Title: Waste-heat heating system
Inventor: MUNDT JUERGEN
IPC: F24J2/04
Filed: 1993-05-29
Abstract: The waste-heat heating system comprises a lamellae exchanger through which water flows and a waste heat-collecting dome, as well as fastenings for hip roof or flat roof. In the case of a flat roof, the system must be mounted on a mast at a height to be determined according to the building, so that the rising air speed does not lead to a build-up of heat under the lamellae. The novel waste-heat heating system is equipped with a flow and return, as well as a condensate conduit. The novel waste-heat heating system can be linked without problems to the novel heating and supply system. It can also be employed for the air-conditioning of buildings and spaces. Use of the novel waste-heat heating system   - During the summer, a temperature of +65 DEG C can be reached with the system. - It is ideal for use in tropical countries. For bathing etc., it is not necessary to produce warm water by other sources of energy. - Furthermore, the resulting condensate can be used as drinking water in hot countries.   The aforementioned is applicable virtually everywhere. In normal use, the warm water is used for domestic purposes. It may, however, also be employed for cooling systems.
